Abstract
A cartridge comprises a powder silo, a mixing frame in the silo, an isolation wall between the powder silo and a powder feed roller and an opening in the isolation wall. A fender is equipped in front of the opening in the isolation wall. The bottom of the fender is separated from the opening. A fender is added between the powder silo and the feed roller to consume the kinetic energy of the carbon powder and change the moving direction of the powder, so the incentive force of the powder is reduced so as to reach the purpose of preventing impacting and avoiding powder leakage. Moreover, the mixing frame can supply powder to the powder feed roller smoothly.
Description
Technical field
The utility model relates to a kind of powder box of used for electronic photography image forming apparatus.
Background technology
At present, normally realize colour print such as electrophotographic image formings such as laser printers in the mode of chromatography, what be that printer adopts is the powder box of four seperate colors, each powder box all has single photosensitive drums structure, a rotating mechanism is set in the printer, four powder boxes circumferentially are provided with along rotating mechanism, according to the color proportioning of wanting print pattern, printer rotates in an orderly manner and switches four powder boxes, finishes the chromatography process on medium.Fig. 1 is exactly the sectional view of this class powder box, powder box comprises the powder-storage bin 100 that holds carbon dust, be located at puddle support 200 in the powder-storage bin, be positioned at powder-storage bin the place ahead powder feeding roller 300, with powder feeding roller 300 contacted photosensitive drums 400, be provided with a partition wall 500 between powder feeding roller 300 and the powder-storage bin 100, partition wall 500 is provided with can be by the opening 600 of carbon dust, and carbon dust is sent on the powder feeding roller 300 by opening 600 from powder-storage bin 100 by the stirring of puddle support 200.When in print procedure, switching powder box, because the action of centrifugal force that the rotating mechanism rotation produces powder box, powder box can be subjected to the impact of the carbon dust in the powder-storage bin, especially carbon dust can directly be poured into powder feeding roller 300 1 sides from the opening 600 of partition wall, this moment, carbon dust can cause very big pressure to the seal of powder box front end, made sealing malfunctioning and cause leaking powder.And, in the transportation of powder box, also can be owing to factors such as concussion produce same problem.
Summary of the invention
The purpose of this utility model provides a kind of powder box with protecting against shock pressure reduction structure.
To achieve these goals, the powder box that the utility model provides, comprise: the powder-storage bin that holds carbon dust, be located at the puddle support in the powder-storage bin, be located at the partition wall between powder-storage bin and the powder feeding roller, be located at the opening on the partition wall, be provided with a baffle plate in the place ahead of partition wall opening, the bottom and the opening of described baffle plate are separated.
According to the technical solution of the utility model, be provided with baffle plate in the place ahead of partition wall opening, when powder box is impacted, when carbon dust is poured into opening, earlier down by the baffle plate retaining, the impulsive force of carbon dust is descended after, just fall into the powder feeding position of powder feeding roller.At this moment,, can not bring very big pressure to the seal of powder box front end, avoid the leakage powder of the excessive generation of pressure because the energy of carbon dust is consumed; Simultaneously since bottom and the opening of baffle plate be separated, complete closed opening not, carbon dust still can pass through from opening part, makes puddle support successfully to powder feeding roller confession powder.
More excellent scheme is that baffle plate and partition wall are shaped on the powder storehouse, and baffle shapes is down L shaped the place ahead of being located at the partition wall opening.
Description of drawings
Fig. 1 is the cut-open view of known powder box structure;
Fig. 2 is the cut-open view of the utility model powder box structure;
Fig. 3 is the utility model powder box powder-storage bin structural representation;
Fig. 4 is the powder box structure cut-open view of another embodiment of the utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is done explanation in further detail.
Embodiment
With reference to Fig. 2, the utility model powder box comprises the powder-storage bin 1 that holds carbon dust, be located at puddle support 2 in the powder-storage bin 1, be located at the powder box front end photosensitive drums 3, with photosensitive drums 3 contacted powder feeding roller 4, between powder feeding roller 4 and powder-storage bin 1, be provided with partition wall 5, partition wall 5 is provided with an opening 50, is provided with a baffle plate 6 in the place ahead of opening 50.In the utility model, powder feeding roller place one side is the place ahead.Baffle plate 6 can be one-body molded with the first half of partition wall 5, also can be the place ahead that independent part is installed on partition wall opening 50.In the present embodiment, baffle plate 6 is shaped on the powder storehouse with partition wall 5.
With reference to Fig. 3, the opening 50 on the partition wall 5 is along partition wall 5 horizontal expansions, and baffle plate 6 also is horizontal rectangle washer, is located at the place ahead of opening 50.Refer again to shown in Figure 2ly, the cross sectional shape of baffle plate 6 is for L shaped, extends back bending downwards from the upper end of opening 50 to powder feeding roller 4 directions.At this moment, baffle plate 6 is positioned at the place ahead of opening 50, and the bottom of baffle plate 6 and opening 50 are separated, make between opening 50 and the baffle plate 6 to have certain interval, and not by baffle plate 6 complete closed.
When printer was worked, the rotating mechanism in the printer was according to the needs of printing, with four powder box rotations that are mounted thereon, to finish the proportioning to different colours.In the process of rotation, carbon dust is subjected to centrifugal action, impact powder box, and pour into the opening 50 of partition wall, owing to be provided with baffle plate 6 in the place ahead of opening 50 from powder-storage bin, after being blocked by baffle plate 6 earlier, carbon dust just falls into the powder feeding position of powder feeding roller, baffle plate 6 has changed the direction of motion of carbon dust and has consumed the kinetic energy of carbon dust, and the impulsive force of carbon dust is sharply reduced, and has reached the purpose of protecting against shock, avoid carbon dust directly to gush out, the seal of powder box front end is caused too big pressure and causes leaking powder.Simultaneously, because the bottom and 50 of the openings of baffle plate 6 have certain distance, do not seal opening 50, the carbon dust that puddle support transports still can be delivered to the powder feeding roller place by opening 50.
In addition, as shown in Figure 4, baffle plate 6 ' can also be a straight plate shape, and from the extension that is directed downwards away from opening 50 of the upper end edge of opening 50,50 of the bottom of baffle plate 6 ' and openings have certain distance, do not seal opening 50, and carbon dust can be passed through from opening part.
